| | <p>'''Cannabis botany''' examines the plant biology of ''Cannabis sativa'' L., covering morphology, physiology, reproductive biology, chemical ecology, and environmental adaptation. As one of humanity's oldest cultivated plants, cannabis exhibits remarkable diversity in growth patterns, chemical profiles, and ecological adaptations across traditional growing regions.</p> |
|

|
| <div class="lw-hero__text"> | | <p>Cannabis is a dioecious annual herb in the family Cannabaceae, characterized by palmate leaves with serrated leaflets, pistillate and staminate flowers on separate plants, and dense resinous trichomes producing cannabinoids and terpenes. The species shows extraordinary morphological variation—from compact highland varieties adapted to short growing seasons to tall tropical cultivars flowering under equatorial photoperiods.</p> |
| <div class="lw-kicker">What this portal is for</div>
| | |
| <p>Botany on Landrace.wiki covers plant identification, morphology, ecology, phytochemistry, cultivation-relevant plant biology, and field documentation workflows (specimens, vouchers, photos, metadata).</p> | | <p>Key botanical themes include photoperiod response and flowering triggers, trichome development and cannabinoid biosynthesis, population genetics and local adaptation, life cycle phenology across climates, and the relationship between environmental conditions and chemical profiles. Modern cannabis botany integrates classical morphological description with molecular genetics, phytochemistry, and population biology to document and preserve genetic diversity.</p> |

| | <p>'''Capitate-stalked trichomes''' are the primary site of cannabinoid and terpene biosynthesis in cannabis. These specialized epidermal structures feature a multicellular stalk topped by a secretory head composed of disc cells that synthesize and accumulate cannabinoids, terpenes, and flavonoids in a subcuticular storage cavity. Trichome density varies dramatically between landrace populations, correlating with environmental pressures such as UV radiation intensity, herbivory pressure, and water stress.</p> |
| |limit=1
| | |
| |order=random
| | <p>Highland varieties from regions like the Hindu Kush and Western Himalayas often display exceptionally dense trichome coverage with high resin production, reflecting adaptation to intense solar radiation at high elevations. Lowland tropical varieties may show sparser but larger trichomes optimized for different environmental conditions. The chemical profile of trichome secretions also varies regionally—some populations produce predominantly THC, others CBD, while many landrace varieties maintain balanced cannabinoid ratios reflecting thousands of years of selection for traditional uses.</p> |
